Is it possible to get lilypond to generate a lilypond source file?

[Bernard Hurley]

Hi All,

I apologise of this has alresdy been answered as I have been ill for a
while and have not been following the list. I looked for an answer but
couldn't find one.

I think it ought to be possible to write a .ly file containing guile
code that makes lilypond do the following:

        1) Read another .ly file
        2) parse that file
        3) convert the resulting music to .ly source code
        4) write this code to a third .ly file

This could be useful if you were, for example writing a fugue. You could
use variables to represent the subject, answer, countersubject etc, and
write a first version using these. This could then be processed as above
to get a version without the variables and \transpose etc, which could
be further edited by hand. I can think of other uses too.

I don't understand the inner workings of lily enough to do it myself at
the moment, but I'm sure it ought to be possible.


Thanks

Bernard
